[PATCH] char: hw_random: bcm2835-rng: removed call to platform_set_drvdata()

[PATCH] char: hw_random: bcm2835-rng: removed call to platform_set_drvdata()

[Andrei Coardos]

This function call was found to be unnecessary as there is no equivalent
platform_get_drvdata() call to access the private data of the driver. Also,
the private data is defined in this driver, so there is no risk of it being
accessed outside of this driver file.

You're right. The platform_get_drvdata call was removed in 
4c04b3729 ("hwrng: bcm2835 - Use device managed helpers").
